Create a function to check if the best_attempt table needs to be updated upon attempt submission

[Gehrkej]

Issue Description:

Currently upon an attempt being submitted the best_attempt table in the database is not being checked and updated if needed.

To-do:

• Fetch best_attempts collection for a drill
• Isolate the best attemepts for a given user
  - [ ] Iterate through all aggOutputs and compare if the new attempt is better (use "lowerIsBetter field" to determine this)
• Update the given field if the new attempt is better

Updated To-dos (4-26-2024)

• More testing on empty leaderboard (no attempts on the board). For testing, delete current entries from an existing leaderboard (in "best_attempts" table of Firebase console)
• Do a bit of manual testing for race case (2 different devices / accounts, try to submit drill at same time)
• Remove unused code to avoid future confusion (updateLeaderboard hook, setManualAttempt stuff in leaderboard.js, etc)

Other Notes:

• Utilize both the updateLeaderboard and useLeaderboard hooks/functions to accomplish this. They are in the /hooks directory

Note: comments on #94 have been made where this function will go. A new feature branch will be made for this issue though

I have this functional for how the "best_attempts" table is currently structured with only having one criterion as well as having each drill being a map/object. See PR #161 for more information.
